  • Fatigue testing of a wind turbine blade
    Patent number: 10209160
    Abstract: The application relates to an apparatus (100) for fatigue testing a wind turbine blade, and to a system and method using such an apparatus (100). The apparatus (100) comprises a base (110) for supporting a first end (12) of the wind turbine blade (10), and an edgewise actuator assembly (120). The edgewise actuator assembly (120) includes a ground-supported edgewise actuator (130) and a flexible cable assembly (140) for connecting the edgewise actuator (130) to the blade (10). The edgewise actuator (130) and the flexible cable assembly (140) are adapted to cyclically deflect the blade (10) relative to the base in the edgewise direction by repeatedly pulling the blade (10) in a substantially horizontal direction.
    Type: Grant

  • Fairing for wind turbine blade
    Patent number: 8475128
    Abstract: The invention relates to a fairing adapted to be mounted on a wind turbine blade (2), wherein the outer surface of said fairing is arranged so as to reduce, when mounted on the blade, the aerodynamic drag in a flapwise (z) direction of the blade. In this way a reduction of the exciter power required in a flatwise fatigue test of the blade is achieved.
